Ambi Wi-Fi appears for devices that are not yet setup (does not have any valid network credentials stored) and has completed bootup succesfully. 

However, there are cases wherein it may not appear timely. The issue may be solved by following these steps:

  1. Power cycle the Ambi Climate device
  2. Wait for the device to finish booting up. Refer to how the LED light is flashing, click here to see what it looks like. 
  3. Refresh your phone WiFi list by toggling it off and on again 

If you have already attempted to connect to Ambi WiFi and it's been stored in your WiFi list, click into it and select Forget network. Try connecting again.
Please note that devices that have already been setup will NOT broadcast Ambi WiFi anymore.
